"We need to speak to him, we don't know if he's a victim, witness or suspect," said police spokesman Mary Walters.
The assault happened Wednesday night and shots were fired, Walters said. No one was injured.
Walters said she didn't have further details and police were still investigating.
Taylor's agent, Drew Rosenhaus, declined comment Friday. Taylor and the Redskins didn't immediately return phone messages seeking comment.
Taylor, who wants a new contract, has been working out in Miami despite pleas from coach Joe Gibbs to join the team in voluntary workouts at their home base in suburban Washington. He signed a seven-year, $18 million deal as the No. 5 overall draft pick in the 2004 draft.
The former Miami Hurricanes standout has had a tempestuous start to his NFL career.
He has fired two agents, was fined for skipping one day of the NFL's mandatory rookie symposium and was accused of spitting on a player during a game at Cincinnati, although he was not punished because the league said there was no video evidence.
He was also charged with drunken driving in October, when he was pulled over at 2:45 a.m. after attending a birthday party for receiver Rod Gardner. Those charges were dismissed in January.
